The issue that you'll run into is that there is one lexical scope that is shared by all calls to Clojure. The only ways around this are (1) run it in another process, and (2) load the Clojure JARs into a ClassLoader at runtime, and throw the ClassLoader away after every call.
The overhead for option 2 is between 0.5 and 1 second per call, because Clojure has to be re-inited. For option 1, it's even more because you are starting Java, then initing Java. Threads have nothing to do with the Clojure lexical scoping. If you run 100 threads, they normally all share the same variables, namespaces, and functions.
